History


Traditional use

Tobacco has long been used in the Americas, with some cultivation sites in Mexico dating back to 1400–1000 BC. Many Native American tribes traditionally grow and use tobacco. Historically, people from the Northeast Woodlands cultures have carried tobacco in pouches as a readily accepted trade item. It was smoked both socially and ceremonially, such as to seal a peace treaty or trade agreement. In some Native cultures, tobacco is seen as a gift from the Creator, with the ceremonial tobacco smoke carrying one's thoughts and prayers to the Creator.


Popularization

Following the arrival of the Europeans to the Americas, tobacco became increasingly popular as a trade item. Hernández de Boncalo, Spanish chronicler of the Indies, was the first European to bring tobacco seeds to the

invented a machine to automate cigarette production. This increase in production allowed tremendous growth in the tobacco industry until the health revelations of the late 20th century.


Contemporary

Following the scientific revelations of the mid-20th century, tobacco was condemned as a health hazard, and eventually became recognized as a cause of cancer, as well as other respiratory and circulatory diseases. In the United States, this led to the Tobacco Master Settlement Agreement, which settled the many lawsuits by the U.S. states in exchange for a combination of yearly payments to the states and voluntary restrictions on advertising and marketing of tobacco products.

Between 2019 and 2021, concerns about increased COVID-19 health risks due to tobacco consumption facilitated smoking reduction and cessation.


Biology


''Nicotiana''

Many species of tobacco are in the genus of herbs ''Nicotiana''. It is part of the nightshade family (

is commonly known as "Virginia tobacco", often regardless of the state where it is planted. Prior to the American Civil War, most tobacco grown in the US was fire-cured dark-leaf. Sometime after the War of 1812, demand for a milder, lighter, more aromatic tobacco arose. Ohio, Pennsylvania and Maryland all innovated with milder varieties of the tobacco plant. Farmers discovered that bright leaf tobacco needs thin, starved soil, and those who could not grow other crops found that they could grow tobacco. Confederate soldiers traded it with each other and Union soldiers, and developed quite a taste for it. At the end of the war, the soldiers went home and a national market had developed for the local crop. * Broadleaf, a dark tobacco varietal family popular for producing enormous, resilient, and thick wrapper leaves. * Burley tobacco is an air-cured tobacco used primarily for

In the U.S., burley tobacco plants are started from pelletized seeds placed in polystyrene trays floated on a bed of fertilized water in March or April. * Cavendish is more a process of curing and a method of cutting tobacco than a type. The processing and the cut are used to bring out the natural sweet taste in the tobacco. Cavendish can be produced from any tobacco type, but is usually one of, or a blend of Kentucky, Virginia, and burley, and is most commonly used for pipe tobacco and cigars. *

Considered the truffle of pipe tobaccos, it is used as a component in many blended pipe tobaccos, but is too strong to be smoked pure. At one time, the freshly moist Perique was also chewed, but none is now sold for this purpose. It is typically blended with pure Virginia to lend spice, strength, and coolness to the blend. *

Production


Cultivation

Tobacco is cultivated similarly to other agricultural products. Seeds were at first quickly scattered onto the soil. However, young plants came under increasing attack from flea beetles (''Epitrix cucumeris'' or ''E. pubescens''), which caused destruction of half the tobacco crops in United States in 1876. By 1890, successful experiments were conducted that placed the plant in a frame covered by thin cotton fabric. Today, tobacco seeds are sown in cold frames or hotbeds, as their

ed in several ways. In the oldest method, still used today, the entire plant is harvested at once by cutting off the stalk at the ground with a tobacco knife; it is then speared onto sticks, four to six plants a stick, and hung in a curing barn. In the 19th century, bright tobacco began to be harvested by pulling individual leaves off the stalk as they ripened. The leaves ripen from the ground upwards, so a field of tobacco harvested in this manner entails the serial harvest of a number of "primings", beginning with the ''volado'' leaves near the ground, working to the ''seco'' leaves in the middle of the plant, and finishing with the potent ''

'' leaves at the top. Before harvesting, the crop must be ''topped'' when the pink flowers develop. Topping always refers to the removal of the tobacco flower before the leaves are systematically harvested. As the industrial revolution took hold, the harvesting wagons which were used to transport leaves were equipped with man-powered stringers, an apparatus that used twine to attach leaves to a pole. In modern times, large fields are harvested mechanically, although topping the flower and in some cases the plucking of immature leaves is still done by hand. In the U.S., North Carolina and Kentucky are the leaders in tobacco production, followed by Tennessee, Virginia, Georgia, South Carolina and Pennsylvania.


Curing

Curing and subsequent aging allow for the slow oxidation and degradation of

s in tobacco leaf. This produces certain compounds in the tobacco leaves and gives a sweet hay, tea, rose oil, or fruity aromatic flavor that contributes to the "smoothness" of the smoke. Starch is converted to sugar, which glycates protein, and is oxidized into advanced glycation endproducts (AGEs), a caramelization process that also adds flavor. Inhalation of these AGEs in tobacco smoke contributes to atherosclerosis and cancer. Levels of AGEs are dependent on the curing method used. Tobacco can be cured through several methods, including: * Air-cured tobacco is hung in well-ventilated barns and allowed to dry over a period of four to eight weeks. Air-cured tobacco is low in sugar, which gives the tobacco smoke a light, mild flavor, and high in nicotine. Cigar and burley tobaccos are 'dark' air-cured. * Fire-cured tobacco is hung in large barns where fires of hardwoods are kept on continuous or intermittent low smoulder, and takes between three days and ten weeks, depending on the process and the tobacco. Fire curing produces a tobacco low in sugar and high in nicotine. Pipe tobacco, chewing tobacco, and snuff are fire-cured. * Flue-cured tobacco was originally strung onto tobacco sticks, which were hung from tier poles in curing barns (Aus: kilns, also traditionally called 'oasts'). These barns have flues run from externally fed fire boxes, heat-curing the tobacco without exposing it to smoke, slowly raising the temperature over the course of the curing. The process generally takes about a week. This method produces cigarette tobacco that is high in sugar and has medium to high levels of nicotine. Most cigarettes incorporate flue-cured tobacco, which produces a milder, more inhalable smoke. It is estimated that 1 tree is cut to flue-cure every 300 cigarettes, resulting in serious environmental consequences. * Sun-cured tobacco dries uncovered in the sun. This method is used in Turkey, Greece, and other Mediterranean countries to produce oriental tobacco. Sun-cured tobacco is low in sugar and nicotine and is used in cigarettes. Some tobaccos go through a second stage of curing, known as '' fermenting'' or ''sweating''. Cavendish undergoes fermentation pressed in a ''casing'' solution containing sugar and/or flavoring.


Global production


Trends

Production of tobacco leaf increased by 40% between 1971, when 4.2 million tons of leaf were produced, and 1997, when 5.9 million tons of leaf were produced.Food and Agriculture Organization of the United Nations. "Projection of tobacco production, consumption and trade for the year 2010." Rome, 2003. According to the Food and Agriculture organization of the UN, tobacco leaf production was expected to hit 7.1 million tons by 2010. This number is a bit lower than the record-high production of 1992, when 7.5 million tons of leaf were produced.The Food and Agriculture Organization of the United Nations.''Higher World Tobacco use expected by 2010-growth rates slowing down.'' (Rome, 2004). The production growth was almost entirely due to increased productivity by developing nations, where production increased by 128%. During that same time, production in developed countries actually decreased. China's increase in tobacco production was the single biggest factor in the increase in world production. China's share of the world market increased from 17% in 1971 to 47% in 1997. This growth can be partially explained by the existence of a low import tariff on foreign tobacco entering China. While this tariff has been reduced from 66% in 1999 to 10% in 2004, it still has led to local, Chinese cigarettes being preferred over foreign cigarettes because of their lower cost.


Major producers

Every year, about 5.9 million tons of tobacco are produced throughout the world. The top producers of tobacco are China (36.3%), India (12.9%), Brazil (11.9%) and Zimbabwe (3.5%).


=China

= Around the peak of global tobacco production, 20 million rural Chinese households were producing tobacco on 2.1 million hectares of land. While it is the major crop for millions of Chinese farmers, growing tobacco is not as profitable as cotton or sugarcane, because the Chinese government sets the market price. While this price is guaranteed, it is lower than the natural market price, because of the lack of market risk. To further control tobacco in their borders, China founded a State Tobacco Monopoly Administration (STMA) in 1982. The STMA controls tobacco production, marketing, imports, and exports, and contributes 12% to the nation's national income. As noted above, despite the income generated for the state by profits from state-owned tobacco companies and the taxes paid by companies and retailers, China's government has acted to reduce tobacco use.

Around 0.25% of India's cultivated land is used for tobacco production. Since 1947, the Indian government has supported growth in the tobacco industry. India has seven tobacco research centers, located in Tamil Nadu, Andhra Pradesh, Punjab, Bihar, Mysore, and West Bengal houses the core research institute.


=Brazil

= In Brazil, around 135,000 family farmers cite tobacco production as their main economic activity. Tobacco has never exceeded 0.7% of the country's total cultivated area. In the southern regions of Brazil, Virginia, and Amarelinho, flue-cured tobacco, as well as burley and Galpão Comum air-cured tobacco, are produced. These types of tobacco are used for cigarettes. In the northeast, darker, air- and sun-cured tobacco is grown. These types of tobacco are used for cigars, twists, and dark cigarettes. Brazil's government has made attempts to reduce the production of tobacco but has not had a successful systematic antitobacco farming initiative. Brazil's government, however, provides small loans for family farms, including those that grow tobacco, through the ''Programa Nacional de Fortalecimento da Agricultura Familiar''.


Problems in production


Child labor

The International Labour Office reported that the most child-laborers work in agriculture, which is one of the most hazardous types of work. The tobacco industry houses some of these working children. Use of children is widespread on farms in Brazil, China, India, Indonesia, Malawi, and Zimbabwe. While some of these children work with their families on small, family-owned farms, others work on large plantations. In late 2009, reports were released by the London-based human-rights group

, claiming that child labor was common on Malawi (producer of 1.8% of the world's tobacco) tobacco farms. The organization interviewed 44 teens, who worked full-time on farms during the 2007-8 growing season. The child-laborers complained of low pay and long hours, as well as physical and sexual abuse by their supervisors. They also reported experiencing green tobacco sickness, a form of nicotine poisoning. When wet leaves are handled, nicotine from the leaves gets absorbed in the skin and causes nausea, vomiting, and dizziness. Children were exposed to levels of nicotine equivalent to smoking 50 cigarettes, just through direct contact with tobacco leaves. Nicotine exposure in children can permanently alter brain structure and function.


Economy

Major tobacco companies have encouraged global tobacco production.

, and Japan Tobacco each own or lease tobacco-manufacturing facilities in at least 50 countries and buy crude tobacco leaf from at least 12 more countries. This encouragement, along with government subsidies, has led to a glut in the tobacco market. This surplus has resulted in lower prices, which are devastating to small-scale tobacco farmers. According to the World Bank, between 1985 and 2000, the inflation-adjusted price of tobacco dropped 37%. Tobacco is the most widely smuggled legal product.


Environment

Tobacco production requires the use of large amounts of
pesticide Pesticides are substances that are meant to control pests. This includes herbicide, insecticide, nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, microbicide, fungicide, and lampri ...
s. Tobacco companies recommend up to 16 separate applications of pesticides just in the period between planting the seeds in greenhouses and transplanting the young plants to the field. Pesticide use has been worsened by the desire to produce larger crops in less time because of the decreasing market value of tobacco. Pesticides often harm tobacco farmers because they are unaware of the health effects and the proper safety protocol for working with pesticides. These pesticides, as well as fertilizers, end up in the soil, waterways, and the food chain. Coupled with child labor, pesticides pose an even greater threat. Early exposure to pesticides may increase a child's lifelong cancer risk, as well as harm his or her nervous and immune systems. As with all crops, tobacco crops extract nutrients (such as phosphorus, nitrogen, and potassium) from soil, decreasing its fertility. Furthermore, the wood used to cure tobacco in some places leads to deforestation. While some big tobacco producers such as China and the United States have access to petroleum, coal, and natural gas, which can be used as alternatives to wood, most developing countries still rely on wood in the curing process. Brazil alone uses the wood of 60 million trees per year for curing, packaging, and rolling cigarettes. In 2017 WHO released a study on the environmental effects of tobacco.

Genetic modification

Because of its importance as a research tool, transgenic tobacco was the first genetically modified (GM) crop to be tested in field trials, in the United States and France in 1986; China became the first country in the world to approve commercial planting of a GM crop in 1993, which was tobacco.


Field trials

Many varieties of transgenic tobacco have been intensively tested in field trials. Agronomic traits such as resistance to pathogens (viruses, particularly to the tobacco mosaic virus (TMV); fungi; bacteria and nematodes); weed management via herbicide tolerance; resistance against insect pests; resistance to drought and cold; and production of useful products such as pharmaceuticals; and use of GM plants for bioremediation, have all been tested in over 400 field trials using tobacco.


Production

Currently, only the US is producing GM tobacco. The Chinese virus-resistant tobacco was withdrawn from the market in China in 1997. From 2002 to 2010, cigarettes made with GM tobacco with reduced nicotine content were available in the US under the market name Quest.


Consumption

Tobacco is consumed in many forms and through a number of different methods. Some examples are: * Beedi (also known as bidis or biris) are thin, often flavoured cigarettes from India made of tobacco wrapped in a tendu leaf, and secured with coloured thread at one end. * Chewing tobacco is the oldest way of consuming tobacco leaves. It is consumed orally, in two forms: through sweetened strands ("chew" or "chaw"), or in a shredded form ("dip"). When consuming the long, sweetened strands, the tobacco is lightly chewed and compacted into a ball. When consuming the shredded tobacco, small amounts are placed at the bottom lip, between the gum and the teeth, where it is gently compacted, thus it can often be called dipping tobacco. Both methods stimulate the salivary glands, which led to the development of the spittoon. *

It is marketed mainly to women in India, and is known by the brand names Ipco (made by Asha Industries), Denobac, Tona, and Ganesh. It is locally known as ''mishri'' in some parts of Maharashtra. * Dipping tobaccos are a form of smokeless tobacco. Dip is occasionally referred to as "chew", and because of this, it is commonly confused with chewing tobacco, which encompasses a wider range of products. A small clump of dip is 'pinched' out of the tin and placed between the lower or upper lip and gums. Some brands, as with snus, are portioned in small, porous pouches for less mess. * Gutka is a preparation of crushed betel nut, tobacco, and sweet or savory flavorings. It is manufactured in India and exported to a few other countries. A mild stimulant, it is sold across India in small, individual-sized packets. * Heat-not-burn products heat rather than burn tobacco to generate an aerosol that contains nicotine. * Dokha is a middle eastern tobacco with high nicotine levels grown in parts of Oman and Hatta, which is smoked through a thin pipe called a medwakh. It is a form of tobacco which is dried up and ground and contains little to no additives excluding spices, fruits, or flowers to enhance smell and flavor. *

If referring specifically to the orally consumed moist snuff, see dipping tobacco. * Snus is a steam-pasteurized moist powdered tobacco product that is not fermented, and induces minimal salivation. It is consumed by placing it (loose or in little pouches) against the upper gums for an extended period of time. It is somewhat similar to dipping tobacco but does not require spitting and is significantly lower in TSNAs. * Tobacco edibles, often in the form of an infusion or a spice, have gained popularity in recent years. * Tobacco pipes typically consist of a small chamber (the bowl) for the combustion of the tobacco to be smoked and a thin stem (shank) that ends in a mouthpiece (the bit). Shredded pieces of tobacco are placed in the chamber and ignited. * Tobacco smoke enemas were employed by the indigenous peoples of North America to stimulate respiration, injecting the smoke with a rectal tube. Later, in the 18th century, Europeans emulated the Americans.

Demographic

Research on tobacco use is limited mainly to smoking, which has been studied more extensively than any other form of consumption. An estimated 1.1 billion people, and up to one-third of the adult population, use tobacco in some form. Smoking is more prevalent among men" Guindon & Boisclair" 2004, pp. 13-16. (however, the gender gap declines with age), the poor, and in transitional or developing countries. A study published in Morbidity and Mortality Weekly Report found that in 2019 approximately one in four youths (23.0%) in the U.S. had used a tobacco product during the past 30 days. This represented approximately three in 10 high school students (31.2%) and approximately one in eight middle school students (12.5%). Rates of smoking continue to rise in developing countries, but have leveled off or declined in developed countries. Smoking rates in the United States have dropped by half from 1965 to 2006, falling from 42% to 20.8% in adults. In the developing world, tobacco consumption is rising by 3.4% per year.


Health effects


Chemicals

Tobacco smoking harms health because of the toxic chemicals in tobacco smoke, including carbon monoxide,
cyanide Cyanide is a naturally occurring, rapidly acting, toxic chemical that can exist in many different forms. In chemistry, a cyanide () is a chemical compound that contains a functional group. This group, known as the cyano group, consists of a ...
, and carcinogens, which have been proven to cause heart and lung diseases and cancer. Thousands of different substances in cigarette smoke, including polycyclic aromatic hydrocarbons (such as benzopyrene), formaldehyde, cadmium, nickel, arsenic, tobacco-specific nitrosamines, and phenols contribute to the harmful effects of smoking. According to the World Health Organization, tobacco is the single greatest cause of preventable death globally. WHO estimates that tobacco caused 5.4 million deaths in 2004 and 100 million deaths over the course of the 20th century. Similarly, the United States Centers for Disease Control and Prevention describe tobacco use as "the single most important preventable risk to human health in developed countries and an important cause of premature death worldwide." Due to these health consequences, it is estimated that a 10 hectare (approximately 24.7 acre) field of tobacco used for cigarettes causes 30 deaths per year – 10 from lung cancer and 20 from cigarette-induced diseases like cardiac arrest, gangrene, bladder cancer, mouth cancer, etc. The harms caused by inhaling tobacco smoke include diseases of the heart and

s, chronic obstructive pulmonary disease (emphysema), and cancer (particularly cancers of the lungs, larynx, mouth, and pancreas). Cancer is caused by inhaling carcinogenic substances in tobacco smoke. Inhaling secondhand tobacco smoke (which has been exhaled by a smoker) can cause lung cancer in nonsmoking adults. In the United States, about 3,000 adults die each year due to lung cancer from secondhand smoke exposure. Heart disease caused by secondhand smoke kills around 46,000 nonsmokers every year. In children, exposure to secondhand tobacco smoke is associated with a higher incidence and severity of respiratory illnesses, middle ear disease, and asthma attacks. Each year in the United States, secondhand smoke exposure causes 24,500 infants to be born with low birthweight, 71,900 preterm births, 202,300 episodes of asthma, and 790,000 health care visits for ear infections.

Economic

Tobacco has a significant economic impact. The global tobacco market in 2010 was estimated at US$760 billion, excluding China. The global revenues from tobacco taxes in 2013-2014 was approximately $269 billion. In China, cigarette manufacturing is one of the few profitable state-owned industries. For example, in 1998 the 1 429 state-owned enterprises in Yunnan province had revenue of

(RMB) 69.1 billion (US$8.3 billion) while 8 cigarette manufacturing plants alone accounted for about 53 percent (or RMB 36.2 billion) of total provincial industry sales. The Chinese government also collects tax on tobacco products. Tax revenues from cigarettes increased from 740 to 842 billion Chinese yuan between 2014 and 2016. This generated an additional 101 billion Chinese yuan in tax revenues for the government. In India, tobacco generates approximately 20 billion Indian Rupees (US$0.45 billion) of income per annum as a result of employment, income and government revenue.

reports that US smoking rates are declining steadily. In terms of health expenditures, cigarette smoking contributed to more than $225 billion (or 11.7%) of annual healthcare spending in the U.S. in 2014. Smoking-attributable healthcare spending increased more than 30% for Medicaid between 2010 and 2014. In the US, the decline in the number of smokers, the end of the Tobacco Transition Payment Program in 2014, and competition from growers in other countries, made tobacco farming economics more challenging. Of the 1.22 billion smokers worldwide, 1 billion of them live in developing or transitional economies, and much of the disease burden and premature mortality attributable to tobacco use disproportionately affect the poor. While smoking prevalence has declined in many developed countries, it remains high in others, and is increasing among women and in developing countries. Between one-fifth and two-thirds of men in most populations smoke. Women's smoking rates vary more widely but rarely equal male rates. Tobacco users must also spend a significant amount of money on cigarettes to maintain regular use, as tobacco products are often heavily taxed by governments. For example, a pack a day smoker in the state of New York would have to spend around $4,690.25 a year on cigarettes alone. In Indonesia, the lowest income group spends 15% of its total expenditures on tobacco. In Egypt, more than 10% of low-income household expenditure is on tobacco. The poorest 20% of households in Mexico spend 11% of their income on tobacco.


Advertising

The tobacco industry advertises its products through a variety of media, including sponsorship, particularly of sporting events. Because of the health risks of these products, this is now one of the most highly regulated forms of marketing. Some or all forms of tobacco advertising are banned in many countries.


Environment

Tobacco does a great deal to pollute the environment. Cigarette bumps or packages can easily end up in seas or lakes. Tobacco, by leading to disease, then leads to environmental pollution. It can drive up medication use. The medication industry in turn contributes to pollution, by the production process, by the disposal of medication, by packaging, etc.
